matrix or for removing it. The case is proshownl in Fig. 1, said case being provided vided withaseries of clam ps,which are adaptwith short legs 27 28, which are adapted to ed to turn down over the side edges of the core rest upon the upper ends of the standards 25 9o 4o when fitted in the case to clamp itin position, 26, as shown in Figs. 1 to 3.

and the frame of the machine is provided with 29 indicates a stop which projects horizoncams adapted toengage arms connected to the tally from the cross-bar 10 and serves to inclamps, so that as the casting-box is swung tercept the rear end of the case 14 when tilted,

upon its truunions the clamps are automatas shown in Fig. 4, said case being providedA 95 ically moved down upon the edges of the core with a pin 30, which is adapted to strike said and tightly bind orlock it in position. A stop, as shown.

suitable counterbalance is provided, which is 31 32 indicate cams, which are secured to attached to the core and serves not only to the inner faces of the side frames 8 9, as

assist in raising the casting-box to its elevated shown in Figs. 3 and 4, said cams in the conloo goposition, but also to raise the core when unstruction herein shown being locateda short locked from the case. The counterbalance distance back of the trunnioned bearings 17 18. The object of the cams 3l 32 is to operate the clamps, as will be hereinafter described. The upper portions of the cams 31 32 are beveled, as shown at 33 in Fig. 3, so that the clamping operation will be gradual, as will be hereinafter set forth.

34 indicates a semicylindrical core which is adapted to tit into 'the case 14 to form the inner member of the mold in the usual Way. The core 34 is of slightly-less diameter than the internal diameter of the case, so as to provide space between them for the matrix and plate. At its rear end the core 34 is provided with arms 35 36, which are pivoted upon the cross-bar 2l, as shown in Fig. 2, so that the core may swing vertically about said rod 21. The core 34 is also provided with a cross-bar 37, which is arranged about midway of the length of the core and projects over the side edges of the ease, shown in Fig. 2, thus serving to prevent the core from entering the case beyond a certain point. rPhe forward end of the core 34 is beveled, as shown at 38 in Figs. 3 and 4, to form a funnel to facilitate the pouring ofthe molten metal into the mold.

39 4() indicate clamps for locking the core in the case. The clamps 39 40 are mounted, respectia'ely, upon shafts 41 42, said shafts being supported in bearings 43 44 at the side edges of the case. 45 indicates collars upon the shafts 41 42 to prevent displacement. The clamps 39 40 are of such length and shape that when rocked in a proper direction by the rot-ation of the shafts 41 42 they will beardown upon the side edges of the core 34, thereby locking the core in place. The shafts 41 42 are rocked to operate the clamps by the cams 31 32 through the instrumentality of arms 46 47, which project from collars 48 49, respectively mounted upon and keyed to the shafts 41 42. The arms 46 47 are provided at their ends with rollers 50 51, respectively, which are adapted to bear against the inner faces of the cams 31 32 when the casting-box is tilted. As shown in Figs. 1 and 3, the rollers 50 51 are adjustably secured in slots 52 in the ends of arms 46 47, so that the pressure of the clamps may be adjusted.

53 indicates a cross-bar secured upon the upper surface of the core 34, which also serves to limit the extent to which the core can move into the case.

54 indicates a shaft which is mounted in bearings 56 57, secured upon the upper surface of the core near its front end, as shown in Fig. 2. The shaft 54 carries at its ends cams 58 59, which are so located as to rest upon the side edges of the case when the core is in place, as shown in Figs. 1 and 2. Said cams are so adj usted that by rocking the shaft 54 they will operate to raise the front end of the core to a small extent out of the case, and their function is to loosen the core after a cast has been made, so that it may be thrown up out of the way. Lever 60 is provided for rocking the shaft 54.

61 62 indicate the usual sidesticks, which are adapted to fit between the side edges of the case and core, as shown in Fig. 5. The rear ends of the sidestichs 61 62 are adapted to fit into suitable sockets in the end ring 63, which closes the rear end of the mold. The end ring 63 is provided with slots 64, adapted to lit over pins 65, carried bythe case, which pins serve to prevent the displacement of the end ring and retain it in position when the core is thrown up out of the case, as shown by dotted lines in Fig. 1.

66 indicates a counterbalance, which consists of blocks 67 68, connected by rods 6), as shown in Fig. 1. The rods 69 are ixedly se cured in the lower block 67, and the block 68 is arranged to move vertically upon said rods. The heads 7() of the rods 69 prevent the upper block from becoming detached from them.

71 indicates a flexible connection connected to the block 68 at one end and at its other end to a staple 2, connected to the cross-bar 37 and carried by the core. The cord or flexible connection 71 runs over a pulley 73.

74 indicates a suitably-arranged support adapted to carry the lower block 67 when it is dropped to a certain point.

The operation of my improved casting-box is as follows: To prepare the box for a cast, the core is unlocked from the case byturning the casting-box to its horizontal position, the unlocking being automatically effected by the movement of the rollers 50 51 out of operative contact with the cams 31 32 and the action of springs 75, which are connected to rearwardly-projecting arms 76, carried by the clamps and to the case, so that they serve to throw the clamps out ot' operative position as soon as the rollers 50 51 move out of operative contact with the cams. The lever 60 is then thrown over to the left, thereby raising the core slightly out of the case and permitting the sidesticks 61 62 to be removed. As soon as the core is disengaged from the case it is raised to the position shown in dotted lines or higher, if desired, the counterbalance assisting in this movement of the core. During the irst part of the upward movement of the core the entire weight of the counterbalance is operative; but as soon as block 67 moves down to the support 74 it rests upon said support, leaving only the up per block 68 eifective, said block then moving down upon the rods 69, as indicated by dotted lines in Fig. 1. The matrix may then be placed in position in the case, after which the core is moved down into operative position and the casting-box tilted to the position shown in Fig. 4, the lever 24 being operated to throw the arms 22 23 out of engagement with the lugs 19 20. As soon as the box commences to rock upon its trunnions the rollers 50 51 move into operative contact with the cams 3l 32, thereby throwing the clamps 39 40 over and down upon the side edges of the core. The pressure is at first gradual, owing to the beveled faces of the cams 31 32, butis increased to the maximum early in the tilting' movement or soon after the tiltingcommences. When the casting-box assumes the position shown in Fig. 4, the cast is made and the box returnedto its horizontal position.

I have described in detail the construction of the casting-box herein shown; but I wish it to be understood that I do not restrict myself to the specific details of the construction shown and described,as various modiications may be made without departing from my in vention. For instance, the position of the cams and oi' the clamps may be varied and various other changes may be made without materially altering the operation of the machine.

That which I claim as my invention, and desire to secure by Letters Patent, is--,
